occupied by a stationary vessel C, so that only a small quantity of water is required 7 for effecting the change.

While the construction of Fig. 1 is more suitable when work is to be performed only during one stroke of the float, that of Fig. 2 is more suitable when both strokes are to be effective. In this construction the pipe a communicates by means of conduits V with the two waters, and the conduits are fitted with slide valves V and V The well F also communicates by means of ports with both sides, the ports being fitted with valves V and V The float A is here shown by full lines in its highest position and in communication with the water W0, the well being in communication with the water l/Vu. The float has thus a tendency to sink in the well and will continue to do so until the valves are changed over, which is effected automatically by any suitable mechanical or electrical means. When the valves V and V are closed, and the valves V and V are opened, the water-heads of the well and of the float will be reversed, and the float w1ll acquire a rising tendency.

I claim:

1. A water power engine, comprising, in combination, two basins containing water, the levels of these two bodies of water being different; a water-shaft communicating with said basin; a hollow float open at its top and arranged in said hollow shaft; control members so arranged as to permit the outer upper water to enter into the float and to rise to the level thereof, whereby the said float is caused to sink; said control members being also adapted to cause the upper water to flow continually into the float while this latter is sinking, and to permit the water present in the float to flow out until its level has reached that of the outer lower water whereby the float is caused to rise, the said control members permitting also the water present in the float to flow out continuously into the lower water while the float is rising, substantially as described.

2. In a water-motor, the combination, with two water-filled spaces having diflerent levels, of a water well communicating with said spaces, a hollow float arranged in said well, a stationary vertical tube forming both a guide for the float anda communication between the interior thereof and said exterior water-spaces, and controlling means by which the exterior high-level water is permitted to enter the float and to rise to the level of said water, whereby the float is caused to sink, and the float water is permitted to leave the float until having fallen to the exterior low level whereby the float is caused to rise, as set forth.

3. In a water-motor, the combination, with two water-filled spaces having different levels, of a water well communicating with said spaces, a hollow float arranged in said well, a stationary water-displacing body arranged within the float and filling up the difference in height between the two exterior water-levels, and controlling means by which the exterior high-level water is permitted to enter the float and to rise therein to the level of said water whereby the float is caused to sink, and the float water is permitted to leave the floatuntil having fallen to the exterior low level whereby the float is caused to rise, as set forth,

4. In a water-motor, the combination, with two water-filled spaces having dijflerent levels, of a water well communicating with said spaces, a hollow float arranged 'in said well, a stationary vertical tube formmg both a guide for the float and a communication between the interior thereof and said exterior water-spaces; a stationary water-displacing body arranged within the float above said tube and filling up the difference in height between the two exterior water-levels, and controlling means by which the exterior high-level water is permitted to enter the float and to rise therein to the level of said water whereby the float is caused to sink, and the float water is permitted to leave the float until having fallen to the exterior low level whereby the float is caused to rise, as set forth.

5. In a water motor, the combination,

with a float of valve-controlled closed conduits whereby said float is alternately set in communication with two water-heads so as to effect a corresponding change of head in, the float, this change altering the buoyancy of the float and causing it in one instance to rise and empty itself gradually of its water contents, and in the other instance to sink and admit a fresh charge of water.

6. In a water motor, the combination, with a float of valve controlled closed conduits whereby said float is alternately set in communication with two water-heads so as to eflect a corresponding change of head in the float, this change altering the buoyancy of the float and causing it in one instance to rise and empty itself gradually of its water contents, and in the other instance to sink and admit a fresh charge of water, and a stationary vessel adapted to flll up partly the space of the float within which the change of water-head takes place.

7. In a water motor, the combination, with a float of valve-controlled closed conduits whereby said float is alternately set in communication with two water-heads so as to effect a corresponding change of head in the float, this change altering the buoyancy of the float and causing it in one instance to rise and empty itself gradually of its water contents, and in the other instance to sink and admit a fresh charge of water, and an upright pipe through which communicawith a float of valve-controlled closed con-T duits whereby said float, is alternately set in communication with two water-heads 'so as to effect a corresponding change of head in the float, this change altering the buoyancy of the float and causing it in one instance to rise and empty itself gradually of its water contents, and in the other instance to sink and admit a fresh charge of water; a

stationary vessel adapted to fill up partly the space of the float within which the change of .w'atenhead takes p1ace;';and an upright pipe through which communication is established between it and the diflerent water-heads, said pipe being so arranged as to guide the said'float. In testimony whereof I aflix my signature.
